For example, FIG. 6A and FIG. 6B are a side view and a top view of a transparent display device of a spatial stereoscopic imaging device according to an embodiment of the present invention. Please refer to FIG. 6A and FIG. 6B at the same time. The spatial stereoscopic imaging device 60 includes three coaxial transparent projection screens 62a, 62b, and 62c with an angle of 120 degrees between them, and is used to drive the transparent projection screens 62a, 62b, and 62c along the A rotary motor 64 that rotates on the axis Z. In addition, the spatial stereoscopic imaging device 60 further includes four projectors L1 - L4 disposed toward the axis Z. As shown in FIG. The spatial stereoscopic imaging device 60, for example, uses a spatial multiplex interpolation projection algorithm to calculate the tangential plane images that each projector L1-L4 is suitable for projecting on the transparent projection screens 62a, 62b, 62c at different positions, and controls the projectors L1-L4 During the rotation process of the transparent projection screens 62a, 62b, 62c, the cut-plane images corresponding to the current positions of the transparent projection screens 62a, 62b, 62c are synchronously projected to display stereoscopic images. By using a plurality of projectors L1-L4 to synchronously project the tangent plane images calculated by the spatial multiplexing interpolation projection algorithm on the transparent projection screens 62a, 62b, and 62c from multiple angles, the performance of the spatial stereoscopic imaging device 60 can be further improved. The resolution, brightness, display frequency and response speed of the transparent display device.

In the above embodiments, the spatial stereoscopic imaging device converts the 3D stereoscopic virtual image into a 2D sliced plane image according to the configuration of the transparent display device and the display plane for displaying on the transparent display device. However, for a transparent display, the images displayed by the inner and outer pixels rotating at the same angular velocity may have optical integral differences. That is, under the same angular velocity rotation, the optical integral of the pixels in the inner circle is higher, and the optical integral of the pixels in the outer circle is lower. However, when the accumulated optical integral of each pixel increases, the optical integral of adjacent pixels will overlap to cause residual image. In this regard, the embodiments of the present invention, for example, adopt means such as changing pixel layout, adjusting display drivers, and correcting display graphics, etc., thereby adjusting display lighting effects to compensate or correct the above-mentioned afterimages, thereby optimizing the quality of stereoscopic imaging.

In the embodiment of changing the pixel layout, for example, the transparent display can be divided into multiple display areas, and the pixel layout in the display area can be determined according to the distance between each display area and the rotation axis of the transparent display. For example, a display area farther from the axis may adopt a higher-density pixel layout, while a display area closer to the axis may adopt a lower-density pixel layout. And corresponding to the change of the pixel layout, the images allocated to each display area are adjusted correspondingly. For example, the spatial stereoscopic imaging device can sample the 3D virtual image according to the pixel density of each display area, so as to capture cut plane images suitable for display on each display area, and drive the transparent display to display the captured cut planes image. In this way, when the transparent display rotates at high speed, the display density of the outer ring (that is, the display area that is farther away from the axis) and the luminous intensity per unit time are relatively enhanced, while the inner ring (that is, the display area that is farther away from the axis) is relatively enhanced. The display density and the luminous intensity per unit time are relatively weakened, so that the optical integrals of the inner and outer pixels are the same, and a consistent three-dimensional display effect is presented. for

In the embodiment of adjusting the display driving, for example, according to the distance between each pixel and the axis in the plurality of pixels of the transparent display, the driving voltage of the pixel can be adjusted to drive the transparent display to display the sectional image. In this embodiment, by adjusting the driving voltage of the pixels in the inner and outer circles of the transparent display, the luminous effect of the pixels in the outer circle can be enhanced. As a result, the optical integrals of the pixels in the inner and outer circles are the same, and a consistent three-dimensional display effect is presented.

In the embodiment of modifying the display image information, for example, the light intensity of each pixel of the tangent plane image can be adjusted according to the distance between each pixel of the multiple pixels of the tangent plane image and the axis, so that the transparent display device displays the adjusted cut plane images. For example, you can increase the brightness value of pixels located in the outer circle of the cut plane image, and decrease the brightness value of pixels located in the inner circle of the cut plane image. Thereby, when the transparent display device displays the adjusted tangent plane image under high-speed rotation, the optical integrals of the pixels in the inner and outer circles of the transparent display device are the same, so that a consistent stereoscopic display effect can be presented.

For example, FIG. 7A and FIG. 7B are schematic diagrams of a method for correcting rotated image data according to an embodiment of the present invention. Please refer to FIG. 7A, assuming that each pixel of the transparent display on the display plane P4 displays a stereoscopic image with the same brightness, then when the transparent display rotates to the display plane P4', the actual imaging will be due to the accumulation of optical integrals, so that The optical integration of adjacent pixels (especially the inner circle pixels) will overlap, and the overlapping part will cause the problem of blurred imaging. In this regard, in FIG. 7B , by adjusting the brightness of the pixels in the inner and outer circles of the transparent display, the brightness of the pixels in the outer circle is relatively increased, and the brightness of the pixels in the inner circle is relatively weakened. When the transparent display rotates from the display plane P5 to the display plane At P5', the actual imaging of each pixel will expand due to the accumulation of optical integrals (relative to the expected imaging), but will not overlap, and a clear stereoscopic image can be generated.

The spatial three-dimensional imaging device and method of the embodiments of the present invention use a single or multiple transparent displays to form a single or multiple display planes, and use image calculation technology to correct or compensate the problem of afterimage overlapping or imaging blur caused by high-speed rotating display. It can improve the brightness, contrast, or image update frequency of the stereoscopic image to achieve a high-quality floating stereoscopic image that can be viewed by multiple people at the same time with a full viewing angle.

Anyone with ordinary knowledge in the technical field may make some changes and modifications without departing from the spirit and scope of the present invention.
